Configure.sh error on ZK nodes

Hello I realize this may be something simple but I'm at a dead end on Google and the forums. We have a simple mapr setup deployed on Ubuntu server 10.4 LTS. At the initial configuration everything went well. I was able to execute all steps in the config document. However after loading data and submitting jobs we've found that the task tracker wasn't starting. Upon trying to reconfigure I am getting this error:

    root@MAPR1:/etc/apache2# /opt/mapr/server/configure.sh -C mapr1,mapr2,mapr3 -Z mapr1,mapr2,mapr3
    Node setup configuration:  cldb fileserver jobtracker nfs tasktracker webserver zookeeper
    Log can be found at:  /opt/mapr/logs/prerequisitecheck.log
    ERROR: Can not find matching ZK node IP based on provided input: mapr1:5181,mapr2:5181,mapr3:5181

I can ping all hosts, both via name and ip, I can resolve forwards and backwards (name => ip ip => name) and this error only occurs on nodes that have the mapr-zookeeper packages installed. All other nodes configure fine, I've tried this with zookeeper running and not running. Any insight into what may be causing this?
